12.12. Debugging systems with energy management capabilities

The processor offers functionality for debugging systems with energy management capabilities. This section describes scenarios where the OS takes energy-saving measures when in an idle state.

The different measures that the OS can take to save energy during an idle state are divided into two groups:

Standby

The OS takes measures that reduce energy consumption but maintain the processor state.

Power down

The OS takes measures that reduce energy consumption but do not maintain the processor state. Recovery involves a reset of the core after the power level has been restored, and reinstallation of the processor state.
